This tool is a simplification of the ballpivoting algorithm. It imagines a bella eating a delaunay traignulation in order to extract a manifold surface.

It requires a single parameter: radius of the fretting ball.



Ball Fretting

Given a uniform sampled filled point cloud returns a tight triangulation.



Input:



■tetr: a set of tetraedrons, nx4 array. If the cloud is not tesselated yet you need to call a delaunay triangulator prior calling this function.

■p : nx3 array, 3D set of points.

■r : the only parameter of the algorithm, the radius of the fretting ball

Output:



■t : triangles ids, nx3 array

■tnorm: normals of triangles with outwards orientation
